Dom,

If you want all the muds to listen on the same port, you'll need to bind
them to different IP addresses. You can do this with the aliasing
feature of Linux's IP stack. It allows you to create virtual interfaces
with different IP addresses.

IANARHU, but in RH9 you'll need to look in
/etc/sysconfig/network-scripts and create your virtual interfaces as
ifcfg-eth0:1, ifcfg-eth0:2 etc... The file format is the same as for
ifcfg-eth0. (IANARHU = I am not a Redhat user).

If you can't tweak the mud software to bind to a specific IP address
rather than listening on all interfaces, bind them to different ports
and use iptables to redirect the traffic from the different virtual
interfaces to the ports.

HTH,

James
